baytrail: print dram configuration
After running the MRC blob print out some information on the training: MRC version, number channels, DDR3 type, and DRAM frequency.
Example output: MRC v0.90 2 channels of DDR3 @ 1066MHz
Apparently there are two dunit IOSF ports -- 1 for each channel. However, certain registers really on live in channel 0. Thus, there was some changes to dunit support in the iosf area.
BUG=chrome-os-partner:22875 BRANCH=None TEST=Built and booted bayleybay in different configs.
